Randomized Controlled Trial Comparative Study
Efficacy of inhaled formoterol in reversing bronchoconstriction.
To evaluate the effectiveness and onset of action of formoterol delivered by dry-powder inhaler in reversing methacholine-induced bronchoconstriction. ⋯ The bronchodilator effect of formoterol at five and ten minutes after methacholine-induced bronchoconstriction was similar to that of fenoterol. Despite being a long-acting bronchodilator, formoterol also has a rapid onset of action, which suggests that it could be employed as a relief medication in cases of bronchoconstriction occurring during asthma attacks.

Diffuse pulmonary ossification is a rare condition of unknown pathogenesis in which mature bone is found in the pulmonary parenchyma. It is almost invariably discovered as an incidental finding at autopsy. ⋯ We present the case of a 75-year-old man in which the chest X-ray showed diffuse interstitial infiltrate. Diagnosis was based on histopathological examination by open-lung biopsy, which revealed interstitial fibrosis with pulmonary ossification.

To determine the effect that re-education of the thoracic and abdominal muscles has on the respiratory muscle strength of patients with cystic fibrosis evaluated over time at the Cystic Fibrosis Outpatient Clinic of the Universidade Católica de Brasília (Catholic University of Brasília). ⋯ Use of the thoracic and abdominal muscle re-education technique increased respiratory muscle strength in the cystic fibrosis patients studied, a finding that underscores the importance of including physical therapy in the treatment of these patients.

To identify any possible relation between lower than predicted preoperative respiratory muscle function and the incidence of postoperative respiratory complications and death in elective thoracotomies and laparotomies of the upper abdomen. ⋯ Respiratory muscle function below the predicted value was found to be related with higher relative risk of postoperative complications in the surgical procedures studied.

To use the forced oscillation technique to evaluate asthma patients presenting positive bronchodilator responses (confirmed through spirometry) and compare the results with those obtained in healthy individuals. ⋯ The modifications provoked by use of the forced oscillation technique were in direct concordance with the pathophysiology of the bronchodilator response in asthma patients, indicating that the forced oscillation technique could be useful as a complement to spirometry in these patients.
